211 The Canaanite, the king of Arad, who lived in the South, heard tell that Israel came by the way of Atharim; and he fought against Israel, and took some of them captive. 2 Israel vowed a vow to Yahweh, and said, “If you will indeed deliver this people into my hand, then I will utterly destroy their cities.” 3 Yahweh listened to the voice of Israel, and delivered up the Canaanites; and they utterly destroyed them and their cities: and the name of the place was called Hormah.

Commentary on Numbers 21:1-3
(Read Numbers 21:1-3)
Before the people began their march round the country of Edom, the king of Arad, a Canaanite, who inhabited the southern part of the country, attacked them in the wilderness, and took some prisoners. This was to lead the Israelites to look more thoroughly to the Lord.
